Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed .lpril 30. 1907. Serial No. 371,129.

To all whom it may concern:

lie it known that we, THOMAS J. McGee and JAMES (Litmonicn, citizens ofthe United States of America, residing at Allegheny, in the county ofAllegheny and tatc of Pennsylvania, have invented certain new and usefulImprovements in liurners, ot' which the following is a specification,reference being had therein to the. t

accompanying drawing.

This invention relates to improvements in burners, and the invention hasfor its object to provide a novel burner for denatured alcohol and gas.

Our invention aims to provide a burner which when placed in operation,will generate gas from denatured alcohol and produce a tlame of greatercaloric intensity than derived from art iiicial or natural gas. In thisconnection, our burner is also designed to use artificial or naturalgas, but we construct the same whereby the gas will he. placed in a morecombustible condition prior to being consumed, thus saving gas andincreasing the heating qualities of the burner.

The present invention is an improvement upon our burner for which anapplication for patent was filed Apliil 15th, 1907, Serial No. 368,358,and in the present invention we have devised novel means for retardingand regulating the flow oi denatured alcohol, also novel means forcontrolling the admission of gas to the burner proper.

The detail construction entering into our invention will helna'einai'ter more fully described and then spta-itically pointed out inthe appended claims, and referring to the drawing forming part of thisspecification, like numerals of reference designate corresponding partsthroughout the several views, inwhich'.

Figure l is a front elevation of our burner partly in section, Fig. 2 isa vertical sectional view of the same.

The burner comprises a cylindrical tasing 1 having a closed end 2, whileits opposite end is closed by a detachable head 3 carrying an inlet pipe4. A set screw 5 is employed for holding the head 3 and the pipe 4 inthe end of the casing l. The casing is provided with a plurality oflongitudinally disposed alining openings 6, and adjacent to saidopenings, we provide the casing with a trough 7 substantially V-shapedin cross section for asbestos 8, the trough and asbestos extending fromone end of the burner to the other.

Connecting with the inlet pipe 4 is a funnel-shaped mixer 9 foradmitting air to the pipe 4 to commingle with the gas admitted to themixer through a pipe 10 extending therein. The inner end of the pipe 10is provided with a nipple ll while the outer end is provided with anelbow 12 connecting with another elbow l4 by a pipe 15, in which is anordinary form of valve it, for controlling the admission of gas to thepipe 10. Arranged above the burner casing l and connecting with theelbow 14 is-a pipe 17, said pipe being connected by el bows 18 toanother pipe it), said pipe being arranged I above the pipe 17 andvertically alining with said pipe and the burner casing l. The end ol'the pipe it) is provided with an elbow 2t) connecting with a pipe 2lleading to a conventional form of valve 22 for controlling the inlet ofdenatured alcohol or gas to the pipes it) and i7. The valve 2'2 connectswith a main supply pipe 23, and a connecting with said pipe isa pilotlight tube 2- which 1 extends forwardly and is bent downwardly andpasses l obliquely under the pipe l7 terminating in close proximity tothe asbestos S at the mixer end of the burner l and at a point above theunperforat ed portion of the casing 1, where the latter receives thedetachable head 3. The pilot light tube 24 is provided with an ordinaryvalve 25, for controlling the flow ot' denatured alcohol through thetube.

Prior to assembling the parts of the burner, we provide the pipe it)with a piece of gauze as, the gauze extending from one end of the pipeto the other and retarding the flow ot' denatured alcohol through saidpipe, at the same time regulating the quantity of denatured alcoholadmitted to the pipe 17. The burner casing l is also provided beneaththe openings ti with apieceoi gauze 27, to prevent a flash-back ot' thetlame ol the burner when in operation.

To place the burner in operation, and use denatured alcohol as a fuel orheating medium, a quantity of alcohot is allowed to flow through thetube 24, whereby it can be ignited upon the asbestos S and provide apilot light. In the mean time, the denatured alcohol admitted to thepipes 19 and 17 is being vaporized by the llame ot' the pilot light, andas soon as a suilicient quantity oi the denatured alcohol has beenvaporized, the vapor or gas becoming heated and expanding will tlow intothe burner and can be ignited. The pilot lightcan then be extinguishedby closing the valve 35. The piece of gauze 2G in the pipe [9 allows thedenatured al cohol to [low steadily through said pipe and enter the pipel7, where the alcohol that. has not been vaporized, in the pipe i9 isvaporized in said pipe 17. This vapor, already warm, is further heatedin pipe 17 before its admission to the mixer. The (plant ityot vapor orgas passing into the mixer 9 can be controlled by the valve 16.

When the burner is used with artiiicial or natural gas, the gas beingheated in the pipes 17 and if) prior to entering the burner expands andis placed in a better com bustiblc condition than it the gas was notheated.

We do not care to confine ourselves to the spccitie form of mixer asdisclosed or to the shape and size of the burner.

What we claim and desire to secure by Letters Patent, is:-

1. A burner for denatured alcohol or gas, consisting of a casing, havingopenings formed therein. a trough for asbestos carried by said casing.adjacent to said openings, an inlet pipe carried by one end of saidcasing. a mixer carried by said pipe. pipes connecting with said mixerand arranged one above the other in vertical alinenn-nt with said lmrneuvalves carried by said pipes. a main supply pipe connecting with thevalve carried by the uppermost pipe. :1 pilot light tube connecting withsaid supply pipe and extending obliquely under the lowermost pipe andterminating above an unperforatetl portion of saitl easing and in doseproximity to the trough for as- In-stos and. :1 piece of gauze arrangedin the uppermost pipe above said burner.

1.. burner for denatured aleohol or ens. consisting 01 a easing havingopenings formed in the top thereof, :1 [)ltl'l" ut gauze mounted in saidcasing beneath the openings and spaced from the top lllelvufl atV-shaped trough for asbestos l()('2li't(l adjacent to said openings, amixer connecting with saiti e: in-4. two communicating pipes conueetiugwith saitl mixer and arranged one above the other in rertieal alinelnentwith saitl casing. gauze ltK'FtlT'd in the uppermost pipe. and a mainsupply pipe ronnecting' x t with said pipe and a valve for controllingthe admission of alcohol or gas to said uppermost pipe. the lnwermostpipe arranged in close proximity to said lllll'llll. and a valve placedbetween the lowermost pipe and the mixer for controlling the admissionof heated vapor or gas to said mixer. and a pilot light tulleeonnert'ing with sziitl supply pipe and extendingobliquely under thelowermost pipe and terminating above the unpertorated portion otsaideasing and in elose proximity to the trough for asbestos.
